Colloidal oatmeal is our hero ingredient in almost all of our products. Our bath soaks and eczema moisturiser are known to provide substantial soothing relief from eczema and other forms of itchy, dry and irritated skin. But why?
I know, I get it, and I thought the exact same thing – oatmeal is oatmeal. How is it going to help my child’s itchy, dry, eczema skin? To satisfy my scientific pharmacist self, I started researching the clinical evidence and research available (that kept me busy for a while!) and after those late night study sessions, I decided to jump right in. Or rather… I stepped into the oatmeal bath carefully holding my little boy and hoping with every bit of my heart and soul for something to wash away the pain of his suffering and ease my guilt.
Why can an oatmeal bath be effective for eczema and dry, itchy skin?
Naturally, the benefits of an oatmeal bath go back to science…
Research shows most of the benefits of having an oatmeal bath come from oatmeal’s chemical structure:
- Beta-glucans hold in water and protect the skin, and may also assist in stimulating collagen production to strengthen the skin from irritation.
- Cellulose and fibre which give oatmeal the ability to soften and moisturise the skin.
- Phenols which have antioxidant and anti-inflammatory properties, helping reduce irritation and itching of your child’s eczema skin.
- Our body contains prostaglandins which cause blood vessels to dilate, resulting in inflamed, irritated skin that can be prone to infection by bacteria and other microorganisms.
- Colloidal oatmeal lowers the levels of prostaglandins, resulting in repaired barrier function and calmed skin.
- Saponins, which are compounds found mainly in grains, and this ingredient gives colloidal oatmeal exceptional cleansing qualities to wash the skin and also take away any triggers sitting on the skin’s surface which can cause irritation and lead to infection.
Is using oatmeal for eczema and itchy, dry skin a new thing?
No! Oatmeal has been used for hundreds of years to soothe itchy and irritated skin. The oldest oat grains were found in Egypt in about 2000 BC and was introduced to North America at the beginning of the 17th century. Colloidal oatmeal started to be used for cosmetic benefits in facial masks as well as for cleansing and relieving itching. In the mid 1900s, colloidal oatmeal became ready to use for skin care and in 2003, the US FDA approved it as a product that can relieve skin irritation and itching.
What new evidence is around to suggest colloidal oatmeal might be effective for my child’s eczema?
Studies have been conducted on colloidal oatmeal, as it has been used for centuries as a topical treatment for a range of skin conditions, including eczema. Extracts of colloidal oatmeal were made with numerous solvents and tested in antioxidant and anti-inflammatory assays. A blind study was also carried out with 29 healthy females who displayed mild to moderate itch with dry skin on their lower legs. After treatment with colloidal oatmeal, results showed significant clinical improvements in skin dryness, roughness and the magnitude of itchiness. These results provided evidence that colloidal oatmeal does contribute to anti-inflammatory and antioxidant properties, benefiting the skin, and may be used to treat the symptoms of eczema (Reynertson KA et al., 2018; PubMed 2018).
In a double blind, active-controlled study researchers aimed to evaluate the efficacy and safety of 1% colloidal oatmeal cream, compared to prescription creams in children with eczema. A variety of ages (ranging from 6 months to 18 years old) were randomised to colloidal oatmeal and prescription cream. The effectiveness of these products was tested using the Eczema Area and Severity Index (EASI) scores, as well as the Investigator’s Global Atopic Dermatitis Assessment (IGADA) scores. The EASI scores showed that prescription cream was not superior to colloidal oatmeal. It was concluded that 1% oatmeal cream was equally effective and safe as the prescription cream, in the treatment of mild-moderate eczema in children (Lisante Et Al., 2017; Medline, 2018).
Another double-blind, randomised, controlled study was conducted by researches where colloidal oatmeal was applied for 15 minutes as an open patch test, and under a patch for 24-48 hours. Results showed no sign of an allergic reaction. In a 2-week, single-blinded study of patients with Fitzpatrick skin types IV-VI, a remarkable improvement in skin brightness was seen within the first day, and continued throughout the study period. These results concluded that using the moisturiser containing colloidal oatmeal twice daily had great improvements in alleviating symptoms of irritated skin (Nebus et al., 2004).
But what is colloidal oatmeal?
When we hear oatmeal bath, it may sound like having a bath with breakfast cereal, but it is not quite what we think. Oatmeal is ground into a fine powder and boiled, making it into a colloid, which is a solution of very small particles suspended in warm water, and because it has been finely ground, it remains evenly dispersed and does not sink to the bottom. This well mixed oatmeal is called colloidal oatmeal. Colloidal oatmeal binds to the skin and forms a protective barrier which helps to lock in moisture, as well as ease inflammation, it also cleanses the skin.
